Lipinskii A. The optoelectronic high-accurate discrete signal processing operational devices

The physical and technical background of the optoelectronic discrete signal processing devices’ creation is developed. This allows to increase the computation accuracy of optoelectronic acousto-optic processors. The physical model of acousto-optic digital signal processor is proposed. The modeling of multiplication and delay operations within the acousto-optic interaction media is performed. The physical limitations of device performance are determined. The mathematical model of light wave diffraction on the acoustic pulse is built using the time-domain vector finite-element method. The core architecture of 128-bit optoelectronic acousto-optic processor is proposed. The estimation of design accuracy and device performance is conducted. The prototype of optoelectronic acousto-optic digital signal processor is designed, and can be successfully used for the construction of multifunctional element base of algebraic optoelectronic processors. Key words: acousto-optic digital processor, digital data, discrete convolution, multiplication with accumulation, acousto-optic interaction for finite-size domain, discrete acoustic power distribution, time-domain vector finite-element method.
